The changeabilities of individual modules of aminoacyl-tRNAs are poorly understood, despite the relevance for evolution, translational accuracy and incorporation of unnatural amino acids. Here, we dissect the effect of successive changes in four domains of Ala-tRNA3Ala on translation in a purified system. Incorporating five amino acids, not one, was necessary to reveal major effects on yields of peptide products. Omitting tRNA modifications had little affect, but anticodon mutations were very inhibitory. Surprisingly, changing the terminal CCA to CdCA was sometimes inhibitory and non-cognate amino acids were sometimes compensatory. Results have implications for translational fidelity and engineering.
